The processes of capacitive mixing a described in an idealistic way, to make clear how a clean renewable power plant from mixing fresh and sea water clear can be constructed and operated. Important is to note that for both technological concepts (i.e. EcCM and DcCM) proof-of-principle experiments have been performed that show the possibility of this technology.
To transform this proof-of-principle into a viable technology, further insight is needed both in the scientific area, i.e. what is happening, as well as in the technological area, i.e. how can we use these principles. The research needed to achieve this objective is at the heart of this proposal. Two key measures will be used to monitor the progress in the technology development program, namely, energy recovery and power density.
The key measure of energy recovery tells us how much of the energy available in the water due to the salinity difference is actually transformed into electricity. To give a considerable contribution to the electricity production, the energy recovery aimed for is high, namely we aim for an ambitious 70%. The key measure of power density describes how much power is generated per unit volume of the power plant. A high power density implies that the power plant can be smaller and less materials are needed. We aim at a power density of 100 W/m3.
These key measures have been selected to show that the capacitive mixing process
can achieve a performance level far over that of a laboratory curiosity. In this way we
can show that the mixing process warrants future development to explore the huge
energy resource contained in the salinity difference between sea and river water.
Based on our conviction that the capacitive principle can be the basis for a completely new green electricity generating device we set the following overall project objective:
To obtain further scientific insight in the capacitive mixing for energy generation and to create innovative designs and technology such that the capacitive mixing can be developed with a power density of 100 W/m3 and an energy recovery of 70%.
